Tim Tebow is training as if an NFL comeback is possible

For a guy about to embark on a career as a college football analyst, Tim Tebow sure is acting like an NFL player ready to return to camp this week.

Tebow signed a TV deal last year after being cut by the New England Patriots, but it's apparent he still holds out hope of reviving his career as a pro quarterback. He's been traveling between Texas, where he works on his throwing mechanics, to Arizona, where he undergoes rigorous workouts.

Tebow admitted being uncertain about his future, telling KSAZ-TV he's putting his faith in God and preparing for whatever might come his way.

"One of my favorite quotes is, 'I don't know what my future holds, but I know who holds my future,'" Tebow said. "And that it gives you peace to just continue to work and go after what your heart desires; and when you do that you don't have any regrets, and I think that's the best way to live life."
